Representative sampling and chemical test reliability in aluminium scrap disputes required fresh adjudication; limitation and penalties were also left open.

Duty demand based only on chemical test reports of very small samples from non-standard aluminium waste and scrap was found insufficient, because the samples were not representative of the whole lot and did not by themselves establish clandestine removal or diversion. The demand therefore required reconsideration on a fuller factual appraisal, including job-work clearances and return of goods. Limitation and penalties under the excise law were also not conclusively invocable, as the record did not adequately address suppression, intent, or the relevant period. The impugned order was set aside and the matter remanded for fresh adjudication, with other issues left open.

Issues: (i) Whether the duty demand could be sustained solely on the basis of the chemical test reports of small samples drawn from non-standard aluminium waste and scrap, and whether the material showed clandestine removal or diversion; (ii) Whether limitation and the penalties under the excise provisions were properly invocable on the facts of the case.

Issue (i): Whether the duty demand could be sustained solely on the basis of the chemical test reports of small samples drawn from non-standard aluminium waste and scrap, and whether the material showed clandestine removal or diversion.

Analysis: The evidence did not establish clandestine removal or diversion of ingots. The dispute turned on the reliability of test results obtained from very small samples drawn from waste and scrap having variable composition and foreign impurities. In such circumstances, the samples were not representative of the entire lot, and the test reports by themselves were insufficient to conclusively determine the recoverable aluminium content for all clearances. The matter also required a fuller factual appraisal, including the surrounding circumstances of job-work clearances and return of goods.

Conclusion: The demand could not be finally sustained on the basis of the test reports alone and required reconsideration.

Issue (ii): Whether limitation and the penalties under the excise provisions were properly invocable on the facts of the case.

Analysis: The order below did not properly address limitation or the date from which the penal provisions operated. The applicability of the extended period and the statutory penalties depended on a fuller examination of suppression, intent, and the relevant period of demand. Since the foundational facts themselves required reappraisal, the penalty and limitation questions also could not be conclusively determined at that stage.

Conclusion: The questions of limitation and penalties were left for fresh consideration by the adjudicating authority.

Final Conclusion: The impugned order was set aside and the matter was remanded for fresh adjudication, with all other issues left open.
